2-4 Connector and Jumper Settings

Connectors are used to link the system board with other parts of the system, including the
power supply, the keyboard, and the various controllers on the front-panel of the system
case.
The power supply connector is the last connection to be made while
installing a motherboard. Before connecting the power supply, please
make sure it is not connected to the power source.
PW1 / 2 (ATX Power Supply Connector)
The power cord leading from the system's power supply to the external power source
must be the very last part connected when assembling a system. The ATX power supply
provides a single 20-pin connector interface, which incorporates standard +/-5V, +/-12V,
optional 3.3V and Soft-power signals. The Soft power signal, a 5V trickle supply is
continuously supplied when AC power is available. When the system is in the Soft-Off
mode, this trickle supply maintains the system in its minimum power state.
The ATX 12V power supply has a new +12V (4-pin) and +5V/3.3V (6-pin) auxiliary
power connector to enable the delivery of more +12 VDC and +5/3.3V VDC current to
the motherboard.
Power-On By Modem
While in Soft-Off state, if an external modem ring-up signal occurs, the system activates
and can be remotely accessed. You may enable this function in the BIOS's Power
Management Setup menu. (See section 3. 5)
